We will see how this works out or if it ever will be realised.Not interested in their multiplayer titles anyways. Also: this will not stop a lot of people. There are players that bought CS 20 times just to cheat again and again.

Also Valve has no monopoly. Not for a very long time now. Just think of Origin, GamersGate, GoG, Battle.net, OnLive...

Of course. Problem is if the competition is actually worse than Steam that's just unhealthy.Origin has too high prices, GoG had this horrible marketing gag that made them untrustable for me. Gamersgate & Greenman are making most of their money selling Steam keys so what's the point of those services? Desura seems okay. But they only have indie-titles.

Also there are only few competitors that aren't also selling Steam keys.(Origin, GoG, TellTale to some extent...)

And it's pretty clear that Steam, at the time, has no real competitors.

Just because their competion is poor by comparison does not make them a monopoly. You can actually buy games from sources outside Steam and redeem the codes on the service, I don't know how to describe this behaviour, but I certainly wouldn't call it monopolisitic or anti-competitive. Valve pay for bandwidth and see no sales money.

Anyway, we all know that Steam isn't designed to some day take all your games away from you and run away laughing. The benefits it gives smaller developers to be seen and get out there obviously goes without saying.

In short, you are old and stubborn. Be trendy and get with the program.
